Date: Mon, 3 Jan 2022 15:21:29 +0100 Message-Id: <20220103142052.470008118@linuxfoundation.org> X-Mailer: git-send-email 2.34.1 In-Reply-To: <20220103142052.068378906@linuxfoundation.org> References: <20220103142052.068378906@linuxfoundation.org> User-Agent: quilt/0.66 MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: stable@vger.kernel.org From: Mathias Nyman commit e4844092581ceec22489b66c42edc88bc6079783 upstream. The Fresco Logic FL1100 controller needs the TRUST_TX_LENGTH quirk like other Fresco controllers, but should not have the BROKEN_MSI quirks set. BROKEN_MSI quirk causes issues in detecting usb drives connected to docks with this FL1100 controller. The BROKEN_MSI flag was apparently accidentally set together with the TRUST_TX_LENGTH quirk Original patch went to stable so this should go there as well.
